Multi-Parts
Drain, manhole and pit covers need to be versatile not only in shape, frame and size, but also in their ability to suit difficult and problem sites. Large pits may require many lids to cover the area – particularly in areas such as pump stations.
Terra Firma composite-fibreglass pit covers are a lightweight solution with fully removable frames for a clear opening and ease of access. From simple two-part covers to large multipart systems, Terra Firma’s unique patented framing systems offer a flexible solution. Nothing is impossible! We’ve got you covered!

*Please note we can also manufacture to a large range of colours and sizes, or match any sample depending on quantity.
